Level 1B – User technical documentation
The information needed to properly use the Level 1B data can be found in Table 1:
- MDS(Metadata Specification): contains the metadata specification of the TROPOMI Level 1b data products
- IODS (Input Output Data Specification): description of the products that are the result from the Level 0 to Level 1b processing
- ATBD (Algorithm Theoretical Basis Document): high level description of the algorithms used in the Level-0 to 1b data processing
- PRF (Product Readme File): description of changes between different product versions and overall quality information (available a few months after launch)
